In this force and motion STEM challenge, students will use the engineering design process to create a fast or s l o w sled. If you are studying force and motion or how friction can affect force and motion, this challenge is the perfect low-prep hands-on activity! *If you would like to make this into a holiday or Christmas challenge, you can call it Santa's sleigh!
